- Stir together soy sauce, lime juice, lemon juice, olive oil, garlic, sugar, cumin and chili powder in a shallow pan.
- Place steak into the pan and make sure to spoon the marinade over the steak to saturate the meat. Marinate for at least 30 minutes, but overnight is great.
- Preheat your grill to 400-500℉. Remove steak from the marinade and place on the hot grill. Cook for 6-10 minutes, then turn and cook for 6-10 minutes more or until steak reaches desired doneness.
- In a large sauté pan over high heat, sauté peppers and onions until slightly soft and charred. Pay close attention so they don’t burn.
- Remove steak from the grill and let rest 10 minutes. When slicing, do so against the grain.
- Serve steak on tortillas with sautéed peppers and onions as well as the toppings of your choice, like guacamole, pico de gallo, fresh lime wedges and cilantro.
